FIG. 1 is an illustration of an example 100 associated with group verification of a transmission source, according to various aspects of the present disclosure. Example 100 shows an architectural depiction of included components. In some aspects, the components may include one or more user devices 102 in communication with a cyber security service provider (CSP) control infrastructure 104 for purposes of obtaining cyber security services. The one or more user devices 102 and the CSP control infrastructure 104 may communicate over a network 106. The CSP control infrastructure 104 may include a security device 108, a processing unit 110, and a security database 112. The CSP control infrastructure 104 may be owned and operated by a cyber security service provider. The security device 108 may be configured to communicate with the one or more user devices 102 and may be communicatively coupled to the processing unit 110. Additionally, the processing unit 110 may be communicatively coupled to the security database 112, which may be capable of storing data associated with providing the cyber security services.

A user device 102 may include a security application 114 and a processing unit 116. The user device 102 may receive the security application 114 from the security device 108. In an example, a first user device may communicate with the security device 108 to receive a first security application 114 and a second user device may communicate with the security device 108 to receive a second communication. In some aspects, the security device 108 may configure the security applications 114 to enable group verification of a transmission source, as discussed herein. The first user device 102 may utilize the first security application 114 and the second user device 102 may utilize the second security application 114 to communicate (e.g., transmit and/or receive) with the security device and/or each other.

The one or more user devices 102 may be physical computing devices capable of hosting applications (e.g., security applications 114, third-party applications, etc.) and of connecting to the network 106. The one or more user devices 102 may include, for example, a laptop, a mobile phone, a tablet computer, a desktop computer, a smart device, a router, or the like. In some aspects, the one or more user devices 102 may include, for example, Internet-of- Things (IoT) devices such as MSP smart home appliances, smart home security systems, autonomous vehicles, smart health monitors, smart factory equipment, wireless inventory trackers, biometric cyber security scanners, or the like. In some aspects, the one or more user devices 102 may include a server computer.

The network 106 may be any wired or wireless digital telecommunication network that permits several nodes to share and access resources. In some aspects, the network 106 may include a combination of one or more of, for example, a local-area network (LAN), a wide-area network (WAN), a campus-area network (CAN), a metropolitan-area network (MAN), a home-area network (HAN), Internet, Intranet, Extranet, and Internetwork.

The processing unit 110 may be a logical unit including a logical component configured to perform complex operations associated with computing, for example, numerical weights related to various factors associated with providing the cyber security services. The processing unit 110 included in the CSP control infrastructure 104 may be configured to configure the security device 108 to provide the cyber security services to the one or more user devices 102.

The CSP control infrastructure 104 may include a combination of hardware and software components that enable provision of cyber security services to the one or more user devices 102. The CSP control infrastructure 104 may interface with the one or more user devices 102 via an application programming interface (API) (not shown), which may include one or more endpoints to a defined request-response message system. In some aspects, the API may be configured to receive, via the network 106, a connection request from the one or more user devices 102 to establish a connection with the CSP control infrastructure 104 for purposes of obtaining the cyber security services. The connection request may include a request to obtain and install security applications 114 and/or to receive the cyber security services.

The API may further be configured to handle the connection request(s) by mediating the authentication request. For instance, the API may receive from the user device 102 credentials including, for example, a unique combination of a user ID and password for purposes of authenticating the user device 102. In another example, the credentials may include a unique validation code known to an authentic user. The API may provide the received credentials to the processing unit 110 for verification. The processing unit 110 may communicate with the security database 112 to authenticate the user device 102.

The security database 112 may include a structured repository of valid credentials belonging to authentic users. In one example, the structured repository may include one or more tables containing valid unique combinations of user IDs and passwords belonging to authentic users. In another example, the structured repository may include one or more tables containing valid unique validation codes associated with authentic users. The cyber security service provider may add or delete such valid unique combinations of user IDs and passwords from the structured repository at any time. Based at least in part on receiving the credentials from the API, the processor 110 may verify the received credentials by matching the received credentials with the valid credentials stored in the structured repository. In some aspects, the security database 112 and the processing unit 110 may authenticate the user device 102 when the received credentials match at least one of the valid credentials. In this case, the cyber security service provider may provide better security services to the user device 102. When the received credentials fail to match at least one of the valid credentials, the user database 108 and the processor may fail to authenticate the user device 102. In this case, the cyber security service provider may decline to provide cyber security services to the user device 102. Additionally, as discussed below in further detail, the security database 112 may store data associated with providing the cyber security services.

When the user device 102 is authenticated, the user device 102 may initiate a connection with the CSP control infrastructure 104 for obtaining the cyber security services. The processing unit 110 may utilize the security device 108 to transmit information associated with the cyber security services to the user device 102.

One or more components (e.g., security device 108, processing unit 110, and/or security database 112, security application 114, processing unit 116) included in the CSP control infrastructure 104 and/or included in the user device 102, as shown in FIG. 1 , may further be associated with a controller/processor, a memory, a communication interface, or a combination thereof (e.g., FIG. 7 ). For instance, the one or more components may include or may be included in a controller/processor, a memory, or a combination thereof. In some aspects, the one or more components included in the CSP control infrastructure 104 may be separate and distinct from each other. Alternatively, in some aspects, the one or more of the components included in the CSP control infrastructure 104 may be combined with one or more of the other components. In some aspects, the one or more of the components included in the CSP control infrastructure 104 and/or the user device 102 may be local with respect to each other. Alternatively, in some aspects, one or more of the components included in the CSP control infrastructure 104 and/or the user device 102 may be located remotely with respect to one or more of other components included in the CSP control infrastructure 104 and/or the user device 102. Additionally, or alternatively, one or more components of the components included in the CSP control infrastructure 104 and/or the user device 102 may be implemented at least in part as software stored in a memory for execution by a processor. For example, a component (or a portion of a component) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by a controller or a processor to perform the functions or operations of the component. Additionally, the one or more components may be configured to perform one or more functions described as being performed by another set of components shown in FIG. 1 .

As indicated above, FIG. 1 is provided as an example. Other examples may differ from what is described with regard to FIG. 1 .

A CSP control infrastructure may provide cyber security services to user devices related to verifying identities of source applications utilized by the user devices for data communication. In an example, a user device may want to utilize a source application to communicate (e.g., transmit and/or receive) data with a destination device (e.g., user device, server, host device) over a network (e.g., Internet). The source application may include, for example, third-party communication applications such as a web browser, an email client, a messaging client, or a combination thereof.

Utilizing the source application to communicate the data may expose the user device to network vulnerabilities such as, for example, adverse effects regarding operation of the user device. In an example, a malicious party and/or the third-party may include connection malware within the provided third-party communication application. In another example, the malicious party may, in an unauthorized manner, install connection malware on the user device. In these cases, when the user device utilizes the source application to transmit the data, the connection malware may determine and introduce malicious content in the transmitted data. In an example, the malicious content may include access information associated with enabling the malicious party to connect with and, thereby, gain unauthorized access to the user device.

The malicious party may intercept the transmitted data to obtain the access information. Further, the malicious party may utilize the access information to connect with and, thereby, gain unauthorized access to the user device and/or to the CSP control infrastructure providing cyber security services to the user device. The malicious party may install system malware on the user device and/or on devices associated with the CSP control infrastructure (e.g., CSP devices). The system malware may be designed to disrupt and/or damage operation of the user device and/or the CSP devices. In an example, the system malware may embed itself within an operating system of the user device and/or a CSP device and may execute an unauthorized transmission of private information stored in an associated memory. In another example, the system malware may execute an unauthorized deletion of data stored in the associated memory. The system malware may also cause other hindrances by adversely affecting the operating system of the user device and/or the CSP device such that the operating system may run slower and/or associated circuitry may emit excessive heat and/or noise, thereby causing damage to the user device and/or the CSP device.

In such cases, the CSP control infrastructure may expend various infrastructure resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) in efforts to mitigate effects of the private information becoming compromised and the hindrances caused by the system malware. Similarly, the user device may expend various user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) in efforts to mitigate effects of the private information becoming compromised and the hindrances caused by the system malware.

To mitigate the above adverse effects caused by the connection malware and/or the system malware, the CSP control infrastructure may maintain a centralized security database including security information. Such security information may enable the user device to determine whether the data transmitted utilizing the source application may potentially include malicious content. As a result, the user device may avoid utilizing the source application to transmit data that may potentially include malicious content.

In some cases, the centralized security database may become unavailable to the user device. In an example, a server computer associated with retrieving the security information from the centralized security database may become unavailable due to, for example, loss of power, loss of network connectivity, malfunctioning of an operating system associated with the server computer, insufficient processing and/or memory resources, or a combination thereof. In another example, access to the server computer by the user device may be blocked by an entity (e.g., government institution, business institution, educational institution) based at least in part on a current location of the user device. As a result, the user device may be unable to access the centralized database, and, therefore, unable to determine whether the data transmitted utilizing the source application includes malicious content. Consequently, the user device may utilize the source application to transmit the data that includes the malicious content, and, as discussed above, expose the user device to unauthorized access by the malicious party.

Various aspects of systems and techniques discussed in the present disclosure enable group verification of a transmission source. In some aspects, as shown in FIG. 1 , a CSP control infrastructure may configure a security device to enable group verification of a transmission source (e.g., a source application), as discussed herein. In some aspects, the security device may maintain a security database including trusted information such as, for example, stored fingerprints that may be associated with trusted source applications known to be in a condition unaffected by malware (e.g., connection malware and/or system malware). Further, the security device may provide the trusted information to the user devices obtaining cyber security services from the CSP control infrastructure. The user devices may store the stored fingerprint information in respective associated memories. The security device may also enable the user devices to install respective security applications to enable the group verification of a source application.

When a transmitting user device is to utilize a current source application to transmit data, the security device may enable the transmitting user device to verify whether the current source application is a trusted application. In some aspects, the transmitting user device may utilize its installed security application to transmit an announcement to the security device requesting verification of the current source application. The announcement may include verification information containing, for example, identification information identifying the current source application and/or a current fingerprint associated with the current source application. The security device may provide the verification information to the user devices obtaining the cyber security services from the CSP control infrastructure. One or more responding user devices, from among the user devices obtaining the cyber security services, that are familiar with the current source application, may respond based at least in part on receiving the verification information. In an example, a responding user device may utilize its respective security application to determine a verification fingerprint based at least in part on an instance of the current source application installed thereon, and may compare the verification fingerprint with the current fingerprint included in the verification information. When a result of the comparison indicates that the verification fingerprint matches the current fingerprint, the responding user device may determine that the current source application is potentially unaffected by malware and/or that the transmitted data may potentially fail to include malicious content. Alternatively, when the result of the comparison indicates that the verification fingerprint fails to match the current fingerprint, the responding user device may determine that the current source application is potentially affected by malware and/or that the transmitted data may potentially include malicious content. The security device may receive responses indicating respective results of the respective comparisons performed by the one or more responding user devices, and may determine whether the transmitting device is to trust the current source application by determining a consensus based at least in part on the respective results. The security device may transmit information regarding whether the transmitting device is to trust the current source application to all user devices obtaining the cyber security services, including the transmitting user device.

In this way, even when the centralized security database is unavailable to the transmitting user device, the security device may enable the transmitting user device to determine whether the transmitting device is to trust the current source application by relying on a group of responding user devices familiar with the current source application. When it is determined that the transmitting device is not to trust the current source application, the transmitting user device may refrain from utilizing the current source application to transmit the data. As a result, the security device and the respective security applications may prevent a malicious party from gaining unauthorized access to the transmitting user device and/or CSP devices. In other words, the security device and the respective security applications may reduce a possibility of private information becoming compromised and/or other hindrances. Additionally, the security device and the respective applications may enable efficient utilization of infrastructure resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and/or user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) for suitable tasks associated with providing the cyber security services.

In some aspects, a processor (e.g., processing unit 110, processor 620, etc.) may transmit verification information including a current fingerprint associated with a first instance of a source application stored on the transmitting device; receive a determination result determined based at least in part on a comparison of the current fingerprint with a verification fingerprint associated with a second instance of the source application stored on another device; and selectively transmit transmission data utilizing the first instance of the source application based at least in part on the determination result.

FIG. 2 is an illustration of an example flow 200 associated with group verification of a transmission source, according to various aspects of the present disclosure. The example flow 200 may include a transmitting user device in communication with a security device (e.g., security device 108) and one or more responding user devices. In some aspects, the transmitting user device and the one or more responding user devices may be similar to a user device 102, discussed above with respect to FIG. 1 . The transmitting user device, the security device, and the one or more responding user devices may communicate with each other over a network (e.g., network 106).

In some aspects, the transmitting user device and the one or more responding user devices may be associated with the security device for purposes of, for example, obtaining cyber security services. To provide the cyber security services, a CSP control infrastructure (e.g., CSP control infrastructure 104) may configure the security device to configure and provide respective security applications to be utilized by the transmitting user device and the one or more user devices. The security device may configure the respective security applications to enable group verification of source applications, as discussed herein.

Further, to provide the cyber security services, as shown by reference numeral 210, the CSP control infrastructure may utilize the security device to determine trusted information and to store the trusted information in, for example, an associated security database (e.g., security database 112). The trusted information may include stored fingerprints correlated with identities of trusted source applications that are known to be in a condition unaffected by malware (e.g., connection malware and/or system malware).

In some aspects, the CSP control infrastructure may utilize the security device to determine the trusted information based at least in part on hashing and/or encrypting connection information indicating one or more parameters associated with the trusted source applications. In an example, during a reference period prior to providing the cyber security services, the security device may receive one or more trusted transmission packets (e.g., transmission data) from one or more trusted source applications. Such one or more trusted transmission packets may include initial connection packets indicating connection information to be utilized to connect with and/or communicate data with the one or more trusted source applications.

Based at least in part on receiving the one or more trusted transmission packets, the security device may determine identities of the one or more trusted source applications. In some aspects, determining an identity of a source application may include determining information identifying the source application. Further, the identity of the source application may be utilized to determine a state of the source application as, for example, being affected by malware or being unaffected by malware.

For a given trusted transmission packet, the security device may determine source information (e.g., source IP address, source port, etc.) associated with a user device that transmitted the transmission packet. The security device may utilize the source information to query a local Internet protocol (IP) table to determine a process identifier associated with a given trusted source application that transmitted the given transmission packet. Based at least in part on an association between the process identifier and the identity of the given trusted source application, the security device may determine the identity of the given trusted source application.

In some aspects, the given trusted transmission packet may include given trusted connection information to enable a destination application associated with a destination device to connect and/or communicate with the given trusted source application. Based at least in part on receiving the given trusted transmission packet, the security device may analyze the given trusted transmission packet to determine the given trusted connection information. In some aspects, the given trusted connection information may indicate information associated with any combination of one or more parameters to be utilized by the given trusted source application and the destination application to connect with and/or communicate with each other.

The one or more parameters may include a cipher suite, a compression method, an elliptic curve (EC), EC point format, a signature algorithm, a certificate timestamp, etc. The cipher suite may identify, for example, one or more encryption algorithms that the destination device may utilize to connect and/or communicate with the user device 102. In some aspects, the one or more encryption algorithms may include, for example, a key exchange algorithm, a bulk encryption algorithm, a message authentication code (MAC) algorithm, etc. The compression method may identify, for example, one or more transport layer security (TLS) compression methods that the destination device may utilize to connect and/or communicate with the user device 102. The elliptic curve may identify, for example, one or more cryptography schemes that are based on algebraic structures of elliptic curves and may be utilized by the destination device to connect and/or communicate with the user device 102. The EC point format may indicate cryptography keys that may be determined based at least in part on pairs of integer coordinates laying on an elliptic curve and may be utilized by the destination device to connect and/or communicate with the user device 102. The signature algorithm may identify, for example, one or more cryptography algorithms that the destination device may utilize to sign messages transmitted by the destination device to the user device 102. The certificate timestamp may identify, for example, one or more types of certificate timestamps to be signed and transmitted by the destination device while connecting and/or communicating with the user device 102.

Based at least in part on determining the given trusted connection information, the security device may determine a given trusted fingerprint associated with the given trusted source application. In an example, the security device may determine the given trusted fingerprint by hashing and/or encrypting a combination of the one or more parameters. Based at least in part on determining the given trusted fingerprint and/or determining the identity of the given trusted source application, the security device may store, as trusted information, a correlation between the identity of the given trusted source application and the given trusted fingerprint.

The security device may likewise store, as trusted information, correlations between identities of the one or more trusted source applications and respective trusted fingerprints. For example, the security device may store, as trusted information, a first correlation between a first identity of a first trusted source application and a first trusted fingerprint, a second correlation between a second identity of a second trusted source application and a second trusted fingerprint, and so on. In some aspects, the security device may store the trusted information in, for example, the security database accessible to the security device.

As shown by reference numeral 220, the security device may transmit the trusted information to the user devices obtaining the cyber security services. Such user devices may include, for example, the transmitting user device and the one or more responding user devices. The user devices may store the received trusted information in respective memories associated with the user devices. Such respective memories may be located locally or remotely with respect to the user devices.

In some aspects, the transmitting user device may install instances of source applications to be utilized to communicate with the security device and/or one or more responding user devices. The source applications may include third party applications such as, for example, email clients (e.g., Outlook application, Gmail application, etc.), web browsers (e.g., Firefox, Chrome, Internet Explorer, etc.), messaging clients (e.g., Slack, Facebook messenger, etc.), social media applications (e.g., Facebook, Instagram, etc.), or the like.

While obtaining the cyber security services during an operation period, as shown by reference numeral 230, the transmitting device may wish to utilize an instance (e.g., first instance) of a current source application to transmit a current transmission packet. The current transmission packet may include an initial transmission packet indicating current connection information to be utilized to connect with and/or communicate data with the current source application. The current connection information may include connection information. For instance, the current connection information may indicate one or more parameters including a cipher suite, a compression method, an elliptic curve (EC), EC point format, a signature algorithm, a certificate timestamp, etc. to be utilized to connect with and/or communicate data with the current source application, as discussed elsewhere herein.

In some aspects, prior to transmitting the current transmission packet, the transmitting user device may utilize the security application to determine whether the transmitting user device is to trust the current source application. In an example, the transmitting user device may determine whether the current transmission packet may potentially include malicious content.

To determine whether the transmitting user device is to trust the current source application, the transmitting user device may determine an identity of the current source application, as discussed elsewhere herein. Based at least in part on determining the identity of the current source application, the transmitting user device may compare the identity of the current source application with identities of trusted source applications stored in the trusted information. When the identity of the current source application matches an identity of a trusted source application, the transmitting user device may determine that the current source application is a trusted source application and/or that the transmitting user device is to trust the current source application. In this case, the transmitting user device may proceed to transmit the current transmission packet. Alternatively, when the identity of the current source application fails to match an identity of a trusted source application, the transmitting user device may determine that the current source application has not yet been verified as a trusted source application and/or that the transmitting user device is not yet to trust the current source application. In this case, the transmitting user device may refrain from transmitting the current transmission packet. Further, the transmitting user device may rely on group verification of the current source application.

For instance, as shown by reference numeral 230, the transmitting user device may determine and transmit verification information associated with the current source application to the security device. The verification information may include, for example, identification information associated with the determined identity of the current source application and/or a current fingerprint associated with the current source application. In some aspects, the transmitting user device may determine the current fingerprint based at least in part on hashing and/or encrypting the one or more parameters indicated by the current connection information, as discussed elsewhere herein. In some aspects, the verification information may include an encryption list identifying the one or more parameters that were hashed and/or encrypted to determine the current fingerprint.

Based at least in part on receiving the verification information from the transmitting user device, as also shown by reference numeral 230, the security device may forward (e.g., transmit) the verification information to all user devices (except the transmitting user device) obtaining the cyber security services. The user devices may utilize the identification information included in the verification information to determine whether the user devices are familiar with the current source application. In an example, a given user device may be familiar with the current source application when the given user device has an instance (e.g., second instance) of the current source application installed on the given user device. In this case, the given user device may operate as a responding user device.

In some aspects, even though one or more responding user devices may be familiar with by way of installing instances of the current source application, the current source application may not have been previously verified because, for example, the one or more responding user devices may have yet to utilize the current source application to transmit data and/or the one or more user devices may have utilized the current source application to transmit data without relying on the group verification and/or the one or more user devices may have utilized the current source application to transmit data prior to obtaining the cyber security services from the security device and/or the CSP control infrastructure.

Based at least in part on determining familiarity with the current source application, as shown by reference numeral 240, one or more responding user devices may determine and compare respective verification fingerprints with the current fingerprint. In an example, to determine a given verification fingerprint, a given responding user device, from among the one or more responding user devices, may utilize its security application to determine a given verification packet to be transmitted by the instance of the current source application installed on the given responding user device. In some aspects, the instance of the current source application installed on the given responding user device may be trusted to be unaffected by malware.

The given verification packet may include given connection information indicating one or more parameters to be utilized to connect and/or communicate with the instance of the current source application installed on the given responding user device. The given responding user device may utilize its security application to hash and/or encrypt the one or more parameters to determine a given verification fingerprint, as discussed elsewhere herein. In some aspects, the given responding user device may utilize its security application to hash and/or encrypt the one or more parameters identified in the encryption list included in the verification information.

The given responding user device may compare the given verification fingerprint with the current fingerprint included in the verification information. When the given verification fingerprint fails to match the current fingerprint, the given responding user device may determine a result indicating that the current source application is potentially affected by malware and/or that the current transmission packet may potentially include malicious content. Alternatively, when the given verification fingerprint matches the current fingerprint, the given user device may determine a result indicating that the current source application is potentially unaffected by malware and/or that the current transmission packet may potentially fail to include malicious content.

In a similar and/or analogous manner, other responding user devices, from among the one or more responding user devices, may determine respective results indicating that the current source application is potentially affected by malware and/or that the current transmission packet may potentially include malicious content or indicating that the current source application is potentially unaffected by malware and/or that the current transmission packet may potentially fail to include malicious content. As shown by reference numeral 250, the one or more responding user devices may transmit the respective results of the respective comparisons to the security device.

Based at least in part on receiving the respective results, as shown by reference numeral 260, the security device may determine whether the transmitting device is to trust the current source application. In an example, the security device may make such a determination based at least in part on determining whether a predetermined amount (e.g., 51%, 66%, 75%, 90%, or 100%) of respective results indicates that the current source application is potentially affected by malware and/or that the current transmission packet may potentially include malicious content or indicates that the current source application is potentially unaffected by malware and/or that the current transmission packet may potentially fail to include malicious content. For instance, when the security device determines that the predetermined amount of respective results indicates that the current source application is potentially affected by malware and/or that the current transmission packet may potentially include malicious content, the security device may determine that the transmitting user device is not to trust the current source application. Alternatively, when the security device determines that the predetermined amount of respective results indicates that the current source application is potentially unaffected by malware and/or that the current transmission packet may potentially fail to include malicious content, the security device may determine that the transmitting user device is to trust the current source application.

In some aspects, the security device may assign weights to the respective results to determine whether the predetermined amount is satisfied. The security device may assign such weights based at least in part on duration of time for which a responding user device may be associated with the security device and/or with the CSP control infrastructure. In an example, the security device may assign a higher weight to a first responding user device that has been associated with the security device and/or with the CSP control infrastructure for a first duration of time, and may assign a lower weight to a second responding user device that has been associated with the security device and/or with the CSP control infrastructure for a second duration of time, the first duration of time being longer than the second amount of time. Based at least in part on assigning the weights to the respective results, the security device may determine whether the predetermined amount of respective results indicates that the current source application is potentially affected by malware and/or that the current transmission packet may potentially include malicious content or indicates that the current source application is potentially unaffected by malware and/or that the current transmission packet may potentially fail to include malicious content.

Further, the security device may update a weight previously assigned to a responding user device based at least in part on determining, at a later time, that the respective result provided by the responding user device was incorrect. In an example, when the respective result provided by the responding user device indicates that the current source application is potentially unaffected by malware and/or that the current transmission packet may potentially fail to include malicious content, and it is discovered, after transmission of the current transmission packet by the transmitting user device, that the current source application was actually affected by malware and/or that the current transmission packet actually included malicious content, the security device may update the weight previously assigned to the responding user device by assigning a new weight that is lower than the previously assigned weight. In another example, when the respective results provided by the responding user device indicates that the current source application is potentially affected by malware and/or that the current transmission packet may potentially include malicious content, and it is discovered later on that the current source application was actually unaffected by malware and/or that the current transmission packet failed to actually include malicious content, the security device may update the weight previously assigned to the responding user device by assigning a new weight that is lower than the previously assigned weight. In some aspects, the security device may update the weight previously assigned to the responding user device based at least in part on resetting (e.g., to zero) the duration of time for which the responding user device is associated with the security device and/or with the CSP control infrastructure.

As shown by reference numeral 270, the security device may transmit a determination result to the transmitting user device. In some aspects, the determination result may indicate whether the transmitting user device is to trust the current source application. In an example, based at least in part on determining that the predetermined amount (e.g., 51%, 66%, 75%, 90%, or 100%) of respective results indicates that the current source application is potentially affected by malware and/or that the current transmission packet may potentially include malicious content, the security device may determine that the transmitting user device is not to trust the current source application. In this case, the determination result may indicate that the transmitting user device is not to trust the current source application such that the transmitting user device may refrain from utilizing the current source application to transmit the current transmission packet. Alternatively, based at least in part on determining that the predetermined amount (e.g., 51%, 66%, 75%, 90%, or 100%) of respective results indicates that the current source application is potentially unaffected by malware and/or that the current transmission packet may potentially fail to include malicious content, the security device may determine that the transmitting user device is to trust the current source application. In this case, the determination result may indicate that the transmitting user device is to trust the current source application such that the transmitting user device may utilize the current source application to transmit the current transmission packet.

Further, as shown by reference numeral 280, the security device may selectively update the trusted information stored in the security database 112, and may transmit the updated trusted information to all user devices obtaining the cyber security services. For instance, as discussed above, the security device may determine, based at least in part on the predetermined amount of respective results, that the current source application is potentially unaffected by malware and/or that the current transmission packet may potentially fail to include malicious content. In this case, the security device may determine that the trusted information stored in this security database 112 is to be updated to include an association of the current fingerprint with the identity of the current source application. In other words, the security device may determine that the current source application is a trusted application. As a result, the security device may store the association of the current fingerprint with the identity of the current source application as trusted information in the security database 112. In this case, the security device may select to transmit the updated trusted information, including the association of the current fingerprint with the identity of the current source application, to all devices obtaining the cyber security services.

As shown by reference numeral 290, the transmitting user device may process the determination result received from the security device. For instance, when the determination result indicates that the transmitting user device is not to trust the current source application, the transmitting user device may refrain from utilizing the current source application to transmit the current transmission packet. Further, the transmitting user device may discard and/or uninstall the current source application and delete associated data (e.g., current transmission packet, current fingerprint, etc.). Alternatively, when the determination result indicates that the transmitting user device is to trust the current source application, the transmitting user device may utilize the current source application to transmit the current transmission packet.

In this way, even when the centralized security database is unavailable to the transmitting user device, the security device may enable the transmitting user device to determine whether the transmitting device is to trust the current source application by relying on a group of responding user devices familiar with the current source application. When it is determined that the transmitting device is not to trust the current source application, the transmitting user device may determine that the current source application may be affected by malware and may avoid utilizing the current source application to transmit the data. As a result, the security device and the respective security applications may prevent a malicious party from gaining unauthorized access to the transmitting user device and/or CSP devices. In other words, the security device and the respective security applications may reduce a possibility of private information becoming compromised and/or other hindrances. Additionally, the security device and the respective applications may enable efficient utilization of infrastructure resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and/or user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) for suitable tasks associated with providing the cyber security services.
